ADJUSTABLE' STOOL.

Specication of Letters Patent.

To all 'whom t may concern Be it known that I, JOHN a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new. land useful Improvements in Adjustable Stools, of which the following is a speci'ca'tion.

This invention relates 'in general to stools, but has more particular reference tov stools of the typey commonly known as music stools or piano stools, and aims to provide a stool of this character which shall be so constructed that the seat may be tilted `or inclined to suit the convenience of the user.

For certain classes of musical instruments, such, for example, as pianos and organs,rin which the finger keysf are used, a stool having a horizontal seat is preferable and is almost universally employed. For other classes of musical instruments7 particularly the mechanical class, such as piano players and pipe organs,y which require considerable force to operate the pedals, it is essential that the stool or bench be inclined toward the instrument so as to throw the weight of the player into the action of the feet. In order to obviate the expense and inconvenience of having two seats of this character for the different uses to which they may be put in the same household or music-room, it has been proposed to make the seats of piano stools and benches adjustable from a horizontal to an inclined position.

My present invention has reference more articularly to a stool of this latter type and iias for its primary Object the provision of an improved means of adjustment, whereby the seatmay be adjusted sothat the stool may be used with the seat in either horizontal `or inclined position, the adjusting means being so constructed that the seat may be readily converted or adjusted from one position to another and be securely supported in both positions on the stool base.

Other objects of the invention will be apparent as the same becomes better understood by reference to the following description when considered in connection with the accompanying drawings. f

Referring to the drawings: Figure 1 is an elevation of a stool embodying my invention; Fig. 2 is an enlarged fragmentary view of my improved seatadjusting means; and Fig. 3 is a longitudinal sectional view taken substantiallyon the line of 3, 3 of Fig. 2.

On the drawings reference character 5 which may be of any/,preferred shape or construction. The centerpost beinginteriorly threaded in the usual manner to4 receivea threaded supporting post 7. This construc-k tion 1s customary in piano stoolsy and'other stools of thisgeneral character and permits a vertical adjustment of the postto yposition the seat at any height convenient tothe user. Inthe present instance the post f'pis` flattened on opposite sides above the threaded portion, as indicated by reference character 8, and is provided at its upper end with a longitudinally projecting bearing stud 9; The seat-11which Ymay be of4 any Well known or preferred construction, has attached to its bottom, by means ofscrewsklyQ this pin or stud are riveted or headed tov permanently but slidingly and pivotally connect the bracket members to the post.

For the purpose of supporting the seat in adjusted positions on the post I have provided the bracket members 13 with a plurality 0f sockets in which the stud 9 is adapted to seat. In the present instance the sockets 16 are formed in bars or plates 17 disposed between the angle members and secured thereto by rivets 18. For convenience in manufacture I prefer to employ two socket bars placed side by side but it will be obvious that the socket member may be formed in one piece or may, if preferred, be made integral with either orboth of the bracket members.

When the stud 9 is'seated in the center one of the sockets the seat is supported by the j y Patented Nov. 10,1914. Application filed Apr128, 1913. Serial N o. 763,980.

designates generally the base of the stool,`

stud in substantially horizontal position, as r shown in Fig. 2, the seat being prevented from tilting by the vpin'and slot connection 14, l5 between the bracket members and the post 7. When it is desired to adjust the seat to tilted position they seat may be raised su'liciently to disengage the stud 9 from the socket and then tilted in either direction about the pin l5 as a pivotal center whereupon the seat may belowered to engage the stud in one of the lateral sockets. The seat Will thereupon assume the position indicated by dotted lines in Fig. 1.

It Will be manifest from the foregoing that I have provided a stool, the seat of which may be readily converted from ahorizontal4 to an inclined position by simply lifting the seat and tilting itl to the required position, whereupon the engagement of tle stud 9 in a socket Willi maintainV the seat in` its adjusted position' and stably support the' same.v4 My improved stool is,- therefore; ca-

pable of-Y use either as' an ordinary pia-no stool,

with the seat in horizontal position,-y or as a stool for use in connection vvith mechanical players, the conversiony of thefstool from one position toY another being. readily ei'ected.

While I have=shown and described a pre-v ferried form ofi my invention, it Will beI obvious: that the details ofconstruction Vdisclosed are capable of considerable modification andi variation Without departure from ,y the essence of the-` invention orl sacrlficlng any of the material advantages thereof.

I claim:

An adjustable stool comprising a base, a 'post rising' from the base and provided at itsuppery end with anupright laterally en- .larged head, the upper portion of the head tapering upwardly to a centrally disposed upstan ing'lug, said head being provided v'v'itli 'transversely alined' projections below 'l in verticalV alinement With the lug, a seat, a pair of bracket members depending from the` seat and embracing` the head of the post'7 said bracket members being provided with longitudinal slots'l receiving the respective. projections, and asocketumemberlocated. bet-Ween theJ bracket members and provided Withv a series ofsockets for individual engagement .With the' lug and arranged on an arc struck fromI thel axis of the projectionsl on the head,- substantially as shown and def IRA- J.
